Is it possible to limit Google Analytics to only track certain events? Note: Tracking all events and then filtering at the dashboard would not be an acceptable solution here.
Context: for a specific problem we have, we are theorizing with installing a GA tracker in several client sites, reporting to a "property" we control. This would be a second GA tracker in addition to the ones they already have (which I understand is possible).
This second GA tracker would only track very specific events relevant to us. The clients would not wish to share other information (eg: page tracking) with us, and getting all clients to create users for us in their GA dashboards with appropriate filtering is not sustainable.
Is this possible? How?
